Don't panic if they wilt for the first few days they all ways do un less ya use wilt spray.
If you are worried about the wilting part a good tip is to take your cuttings and put them into water straight after the cut for 24 hour it will do them no harm at all,in fact they would root in it if you leave em there long enuf,but takes a week or so extra.
Most people takeing clones for the first time all aways take more than you need so if ya want one take 2/3.
Look for a nice looking clone with a few nodes that ya can take off,make a cut just below it at a angle,with a clean razor or stanley blade make sure everything is clean.Then straight into water the longer its out of water the more chance of air getting trapped in the stem.
Before putting rooting gel on the cut, use a stanley blade to just carefully take about 5mm of the out skin of the bottom of the clone,just the outer skin
Use a rooting gel or powder but don't over do it a lot is not needed,in fact i often don't use any at all they just take a bit longer
.
Make a hole in what ever ya putting the clone in i use rock wool,i make the hole with a kebeb skewer and make the hole round about the full length of the stem,take a bit more of the bottom and plant,if you need to so the full stem is in the medium,so the only thing on top of the medium is the top.This will help you with wilting if the full stem is in say rock rool has a eg ;then it won't wilt has much after all its the stem that normaly wilts worste.
After you have taken the clones that you need either put a zip lock bag,but make sure a little air can get in.Leave it over them for 2 day's but mist twice a day have them on 18/6,if you have a propagator use that because it has vents on it that you can open after the 2 days with them closed.after 2 days of have the vents open the clones should be looking far better now.
This is the time that i take my propagator lid of and just leave them under a t5 light cfl or flouresent tube will do,after that be patient they will root it might take 7 days it might take 15/16 days but they will root most new cloners rush things and because we get them to root in 7/14 days if there have not they think that there's are never gonna root they will.
Misting 2 times a day for 2 days,then once a day after that for 7 days.then just every so often say 3 times a week the more you mist after a week the less they have to work for water,so just mist say like i said 3 times a week under the leaves and the tops .
Make sure that the medium does not dry out but you also do not want it too wet ,just damp.I would advice useing a medium that you can see the bottom off clear cups,are one thing you can use because you can see if any roots are through, rock wool,or jiffy plugs,these would be my first choice.
If you can get some b1 like superthrive then just add a drop to a ltr of water and soak the cubes in it they love the b1 clone's.
Try the leaveing in water for 24 hour this will help with wilting,make sure you dont put the bottom of the clone through the bottom of the rock wool cube ya want to be around 5mm / 10mm from bottom of the medium 5mm been my option,why i use a kebeb skewer gage the length of the stem against the cube,in soil this is not needed but make the cut / stem longer because you need to be around 5 /10 mm from bottom of medium.
